Abstract: The development of the KFA-Precipitation Process for the production of ThO$_{2}$ and (Th, U)O$_{2}$- fuel kernels for the high-temperature reactor is described. Special considerations are given to the refabrication of kernels from high radioactive fuel solutions of reprocessing plants.The process is based on gelation of ThO$_{2}$ and (Th, U)O$_{2}$-sol droplets by NH$_{3}$-absorption in an organic phase of methyl isobutyl ketone. Thedried and fired fuel kernels are produced in a remote and continuous manner. Special studies have been made on the following process steps: - generating drops of uniform size at high frequency within a liquid - continuous washing of gelparticles - continuous drying of gelparticles
